To all whom it may concern: I

Be it known that I, THOMAS WILBUIrr ADAMS, a citizen of the UnitedStates, resid- I ing at Collinwood, in the county of Cuyahoga and Stateof Ohio, have invented new I anduseful Improvements in Switch-Signals, f

'therefromnvhether thesWitch is open or closed; i"

'minals of the circuit being arranged adja- "showing the switch point atits operative 'candescent light or the like located at a 'the track onwhich the train is traveling.

jof which the following'is'a specification.

The invention relates to an improvement t in a" signal device designedprimarily for I use in connection with switches, and adapted when innse'to ndicate ata point remote The main object of the present invention 18the provlsion of a signal, such as an 1npoint remote from the switch andincluded in anorn'ially open circuit, the spaced tercent the switch andbeing adapted to be closed to control the circuit and energize thesignal when the switch points are operated to produce an undesirablecondition on ,The invention in its preferred details bf constructionwill be described in the following specification, reference being badparticularly to the accompanying drawings, in which V Figure l is a planillustrating the im provement. Flg. 2 1s a perspective new position toclose the circuit. ltig. 3 is an enlarged transverse section through thepush button and rail. Fig. 4 is an elevation of the signal. i

Referring particularly to the aceom )anying drawings, my improvement isdesigned to be applied to rails 1 of the main track and controlled byone of the points 2 of the switch.

For the purposes of the invention l arrange at points remote from theswitch and Specification of Letters Patent.

, arranged to engage the strip 7 and terminally project through thecasing S. An arm 10 is secured to the switch point and formed with alaterally otl'set terminal portion 11 adapted to engage the push button9 when the point. is set and through the movement of said push buttonclose the circuit to once gize the signals 3.

ll preference the signals are supported by a standard including anupright 12 and a lateral upper section 123, both of which are hollow forthe reception of the circuit wires. The free end of the section 13supports a casing 1+ preferably provided with glass or other transparentsides. and the signal 3 is arranged within said casing and is preferablya red globe. so that upon energization the rcdor danger signal will beflared from the casing immediately upon closing of the switch againstthe main track.

The signals ii are located in opposite directions beyond the switch sothat the engineer or other operator can be advised some distance beyondthe switch as to the condition ot the latter with respect to the maintrack. it being noted that it is impossible to close the switch properwithout closing the circuits and energizing the signals. I

llaving thus described the invention. what I claim as new, is

The combination with a main track and switch therctor'ofa signal systemincluding a normally open circuit. a signal arranged in said circuit, acircuit closer 't'orming the tcrminals'oi' the conductors of saidnormally open circuit. said circuit closer including a plate to besecured to the web oi the rail and provided with a casing. springcontacts arranged within the casing. a push button normally projectingthrough one wall of the casing by means of the resiliency of one of aidcontacts, and an arm secured to and projecting beyond one of the switchpoints, said arm being formed with an offset portion to overlie andoperate the push button to close the circuit when the switch set in adeterminate position.

In testimony whereof I atiix my signature in presence of two witnesses.
